This invention relates to a combined beater and vacuum cleaner forfabricated material.

An object of the invention is the rovision of a beater in the form of acy inder having blades movable through an o ening in a ycasing of thedevice for perio ically beating the car et while the suction devicewithdraws the irt agitated by the beater.

A further object of the invention is the provision of a beater in theform of a cylinder which is adapted to be revolved adjacent an openingin a housing, a cylinder enclosing a pressure block for maintaining apluralit of elastic holders in operative relation with blades and inengagement with -the inner walls of the cylinder whereby the blades,elastic holders and block may be readily removed from the c linder.-

This invention will' be st understood from a consideration of thefollowing detailed description, in view of the accompanying drawingsforming a part of the specification; nevertheless it is to be understoodthat the invention is notconfined to the disclosure, being susceptibleof such changes and modifications which shall .de-

fine no material departurev from .the salient features of the inventionas expressed in the ap ended claims. L

Referring more particularly to the drawings, 10 designates a casing orhousing hav- W ing a reduced portion at 11 to provide a transverse vel-`discharge passage 12 which opens at 13`into a bag 14 for collecting thedust and dirt from the materialwhich is being cleaned. A handlev 15 isconnected in any approved manner in a housing 10 and carries electricwires -16 and which are connected with `a motor 17 in an auxiliaryhousing 18 to'which the wires 16 are adapted to be connected in anytapproved 'manner with the house curren The bottom of the housin as shownat 20, is flat and vis adapted. telic in close association with thecarpet which is `to be cleaned. The bottom is provided with an opening.21 which connects the interior of the housing with the atmosphere. Aortion of the base, as shown at 22, iso set from the plane of theportion 20 and is provided with an o ening 23 for the purpose ofinspecting t e interior of the housing 10 an for acilitating repairs tothe mechanism within the housing. The opening 23 is adapted to be closedby a door 24 slidably mounted in grooves 25 formed in the bottom portion22. Casters 26 support the elevated base portion 22 in the floor toprovide means for readily conveying the sweeper over the carpet.

The motor 17 drives a fan 30 which is se.- cured toa shaft 31 rojectingbelow a fan housing 32'which' is in communication with the passage 12. Apulley 33 is secured to the lower end of the shaft 31 and has trainedthereon a belt 34 which`is also trained pon,

ulle 35. y

he ater is shown more articularl in Figs. 2 to 7 inclusive, and inc udesa air of cylinders generally designated by t e numerals 40 and 41 whichare normally closed at their outer ends by means of caps 42 and 43,respectively. Closures' 43 and 44 are connected `to the inner ends ofthe cylinders inany approved manner. The pulle 34 is rigidly connectedwith the inner a jacent ends 43 and 44 so that the air of cylinders arerevolved simultaneous y. The outer ends 42 and 43 of the cylinders 40and 41, res actively, are made convex so that they wil fit in sockets inthe end walls of the housing 10.

Each cylinder is provided with a longitudinal slot 45 appeoximately '120apart although any num Y r of slots may be provided which will besuilicient for the purpose. These slots are formed by slitting eachcylinder longitudinally and-bending theportion of the metal on oppositesides of the slit inwardly as shown at 46 to provide a reinforced edge47 for a pur ose which will be presently explained. A triangularlyshapedblock 48 is ocated centrally of each cylinder and is provided withspaced angle irons 49 at each face 50 of the block 48 to provide a seatfor a metallic U-shaped member 51. In two of the seats are mounted apair of elastic holders 52 which are complementaril formed and extendlongitudinally o the U-shaped member 51. 'The inner or bottom portion ofeach member as shown at 53 is cut away to provide a space between thebottom of the U-shaped member and the bottom of the holders 52. holderis provided with a groove 54 to receive a flange 55 of a blade 56 whichis T- v will be seen by sha ed in crossl section. The outer longitudinaled e of each section of the holder is sheared o at an angle and engagesa por,- tion of the inner wall of the cylinder. It will be noted thatthe blades 46 as shown in Figs. 2 and 3 are formed in sections and arespaced from each other throughout their length. The outer ends of theblades project over the outer face ofthe co-operating sections 52 of theholder, as shown at 58. The portions of the holders, as shown aty 59,extend between each blade 56 for spacing the blades longitudinally ofthe holder.

The blade 60 instead of being formedy in sections extends approximatelythe length of the associated holders 61 and since the blade extendsthroughout the approximate length of a holder the spaced members 59 ofthe holder shown in Fig. 3 are omitted. However, the undercut grooves 54are formed in the associated sections of the holder to receive theflanges of the blade for securing the blade in position. The oppositeends of the blade adjacent the cuter surfaces of the sections of theholder are extended, as Ashown at .62, to overlap the portions of theholder adjacent their ends. It this construction that when the block 48is inserted within the cylinder and that nthe sections of the holderswhich are readily moved into the resilient section 71 of the holder.

Each

. 'mounted Lusen shown at 75, are bent outwardly and returned upon thecylinder to provide a reinforcing iange or rib. The blade 56 projectsthrough the slot and has its fianged ends 55 secured within the undercutgrooves witlin he bottom of the sections, as shown at 77, are cut awayto reduce those portions of the sections adjacent 'the bottom 78 of thevU-shaped trough or member 51.

By the above construction it will be seen that the beater may bereadilyassembled or disassembled without the necessity of the employment ofscrews or bolts or any fastening means whatever. It is only necessary toslide the block 48 in its place within the cylinder and -then to insertthe sections of the holder which is mounted within the U-shaped member41 between the angle irons 49. The elastic sections of the holder permitthe blades 56. or 60 to be moved inwardly Furthermore, the elasticity ofthe sections of the holders themselves permit the sliding inwardmovement of lthe blades. Furthermore, when the block 48 is moved intoposition it will force the sections of the holder outwardly and causethem to frictionally engage the portions of the inner wall of thecylinder adjacent the slots 45.
